Quality Daily Physical Education Will Reduce Adult Breast Cancer

New research has revealed yet another reason why quality daily physical education is a must for all students. The study, conducted by Dr. Graham Colditz of the Washington University School of Medicine, found that exercise beginning in the teen years can protect girls from breast cancer when they become adults.

The study tracked 65,000 nurses, questioning them about their activity levels starting at the age of 12.

It was found that the women who were active from their teen years through young adulthood were 23 per cent less likely than sedentary women to develop pre-menopausal breast cancer. It was found that the age period that was most important for sustaining activity levels was 12 to 22.
How much exercise? The women with the lowest risk performed three hours and 15 minutes of vigorous exercise, such as jogging or team sport, per week, or 13 hours per week of walking.

It is believed that exercise reduces women’s lifetime exposure to estrogen, one of the hormones that has been linked to breast cancer.

What is the best way to ensure that girls get this exercise and learn the skills they need to continue into adulthood? Mandatory daily physical education classes – taught by professionals whose focus is on lifetime fitness improvement. Make daily exercise mandatory, and teens will participate. And if they exercise on a regular basis, it will become a healthy habit they will continue throughout their lives.

Breast cancer is the leading cause of death among women around the world, with 1.3 million new cases diagnosed every year, resulting in 465,000 deaths.
